At these depths, there is no sunrise, no seasonal light variation, and no visual horizon. The shark navigates a world defined entirely by pressure waves, chemical traces, and faint bioluminescent signals.
Such existence challenges surface-based assumptions that sight dominates predation. In the deep ocean, life thrives without the primary environmental cue that shapes most terrestrial ecosystems: light.
